Die Oxydation von CO an Katalysatoren auf der Basis poröser Gläser

Oxidation of CO over Catalysts Supported by Porous Glasses It is reported on the catalytic activity of metal catalysts (Ag, Mn, Ni, Cu/Zn, Fe/Cr) supported by porous glasses for the oxidation of CO. In comparison with impregnated carrier catalysts metal catalysts prepared by ionexchange of porous glasses (Ag⁺) show a higher activity for oxidation of CO. The preparation of ionexchanged forms of porous glasses is described.     

Diskrete polynukleare Metall-Komplexe aus Polysulfid-Lösungen: [Cu6S17]2−, ein ungewöhnlicher binärer CuI-Komplex mit verschiedenen bemerkenswerten strukturellen Eigenschaften

Discrete Polynuclear Metal Complexes from Polysulfide Solutions: [Cu₆S₁₇]^2?, a Novel Binary Polynuclear Cu^I Complex with Several Remarkable Structural Features The complex [Cu₆S₁₇]^2?, obtained from Cu(acac)₂ and an ethanolic polysulfide solution, contains an unusual arrangement of the metal atoms and novel types of ligand coordination, particularly of polysulfido (S₄^2? and S₅^2?) ions. The relevance of the synthesis with respect to the “dilemma of transporting metals together with sulfur” for the process of metal sulfide rock formation is evidenced. (PPh₄)₂[Cu₆S₁₇] crystallizes in the space group C2/c with Z = 4 (for further details see Inhaltsübersicht).
